Product Description:

The MKE118B-024-BP0-KUN is a servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Designed for drives installed in potentially explosive areas, it converts regulated electrical power into controlled mechanical torque while meeting UL and CSA housing requirements. The wiring is routed through a top-mounted terminal box, simplifying straight-up conduit runs, and the shaft has a DIN 6885 keyway for positive coupling. Position feedback is supplied by an S2 optical single-turn EnDat 2.1 encoder, letting automation controllers detect absolute rotor position immediately after power-up.

At a 60 K winding temperature, the motor supplies a continuous standstill torque of 28.0 Nm, allowing axes to hold load without external brakes. Generating that torque requires a continuous current of 15.3 A, and the power electronics and cabling are sized for this thermal steady-state value. For rapid acceleration, the electromagnetic system can reach 102.0 Nm in short bursts. Shaft speed is mechanically limited to 4000 rpm, supporting high-speed packaging or spindle duties while avoiding critical resonance. During such transients, the inverter may deliver up to 69.1 A RMS, so the connected drive system must tolerate this peak rating.

The motor’s embedded encoder delivers 2,048 increments and provides absolute data, removing the need for homing cycles. A rotor inertia of 0.01940 kgm² balances fast acceleration with stable settling on direction reversals. The frame mass of 45.0 kg adds damping and increases thermal capacity during intermittent overloads. Back-EMF sensitivity stands at 130.0 V/min⁻¹, giving the controller a predictable voltage-to-speed relationship for diagnostic checks. Operational noise is held to 61.1 dB[A], and a shaft seal is installed to help keep dust or process fluids out of the bearing zone.
